Elemental analysis of nanodiamonds by Atomic emission spectroscopy (AES) (CAT#: STEM-ST-0172-WXH)

Introduction

Detonation nanodiamonds (NDs) gain much attention for biomedical and clinical applications and high-technology purposes due to their unique properties. NDs are technological products that contain not the diamond substance only, but also various kinds of accompanying substances. These substances vary in nature and are present in relatively large amounts. They are formed either during the detonation synthesis itself or in subsequent processing of the diamond mixture.




Principle

Atomic emission spectroscopy (AES) is a method of chemical analysis that uses the intensity of light emitted from a flame, plasma, arc, or spark at a particular wavelength to determine the quantity of an element in a sample. The wavelength of the atomic spectral line in the emission spectrum gives the identity of the element while the intensity of the emitted light is proportional to the number of atoms of the element. The sample may be excited by various methods.

Applications

Common applications of atomic emission spectroscopy are in the analysis of trace elements in soils, water, metals, biological specimens, clinical specimens, food, physical evidence such as glass, and other solids.

Procedure

1. Prepare sample for analysis
2. Convert solution into aerosol
3. Introduce aerosol into excitation source
4. Atomization and excitation
5. Detection of emission lines
